Python 3.10 incompatibility

[alex-golts]

Currently fuse is incompatible with Python 3.10.x

for example, I encountered an ImportError: cannot import name 'Iterable' from 'collections'
because they changed the structure of the collections module and it needs to be imported as:
from collections.abc import Iterable rather than from collections import Iterable

Maybe there are other compatibility issues as well, for now I just reverted back to Python 3.7, but we should solve it sometime...

I'm attaching the relevant source in the documentation here for further use.
Also I think we won't be able to support python 3.10 until all of our dependencies will..

I think I'll add this issue to the stack of my tasks. (ISIC is last runs + now finishing DDP). What is your opinion?

btw:
Just changed two lines in the code and the mnist example is running OK with python 3.10.
Also encountered this PL's issue as a reference.

Update:

I ran python ./run_all_unit_tests.py locally (lsf 3 machine) and got the following:
